One of the feared complications during labor is insufficient strength in uterine contractions.

In this study three groups of women with an initial uterine inactivity were investigated: one group (11 women) was treated with re­lax­ing Medical Resonance Therapy Music^®, a con­trol group A (11 women) listened to music of Mozart – Symphony No. 28 and Coronation Mass – and a control group B (11 women) did not listen to any music at all.

The music treatment was started in the first phase of labor. Strength and rhythm of uter­ine contractions were measured three times for about 10 minutes: shortly before listening to the music, in the middle of the one hour music treatment and shortly after finishing the treatment.


Medical Resonance Therapy Music^® Group

Significant changes could only be docu­mented in this group: the initial weak con­trac­tions of the uterus increased in strength by 60% on average and got more harmonious in rhythm.


Control Group A and B

No significant changes in strength and rhythm of uterine contractions were found.
